Portable electronic device and operation method thereof
An operation method for a portable electronic device is provided. The portable electronic device includes a micro-controller, a ringing module, a g-sensor and an image capturing module. The operation method includes the following steps. When the ringing module is started up at a pre-set time, the g-sensor detects whether the portable electronic device is slanted. If the portable electronic device is slanted, the micro-controller enables the image capturing module to perform human-eye recognition. If human-eye recognition is performed successfully and lasts for a specific period, the micro-controller disables the ringing module.
1. An operation method applicable to a portable electronic device comprising a micro-controller, a ringing module, a g-sensor and an image capturing module, the operation method comprising:
controlling the g-sensor by the micro-controller to detect whether the portable electronic device is slanted when the ringing module is started up at a pre-set time;
enabling the image capturing module by the micro-controller to perform human-eye recognition if the portable electronic device is slanted; and
disabling the ringing module by the micro-controller if human-eye recognition is performed successfully and lasts for a specific period.
2. The operation method according to claim 1 , wherein the step of detecting whether the portable electronic device is slanted comprises:
detecting by the g-sensor whether the portable electronic device is supported such that the angle contained between the portable electronic device and a horizontal plane is larger than a first angle; and
determining by the micro-controller whether the portable electronic device is perpendicular to the horizontal plane if the portable electronic device is supported such that the angle contained between the portable electronic device and the horizontal plane is larger than the first angle.
3. The operation method according to claim 2 , wherein the first angle ranges between 80˜90°.
4. The operation method according to claim 2 , wherein the step of detecting whether the portable electronic device is slanted further comprises:
detecting by the g-sensor whether the portable electronic device is slanted to a second angle; and
determining by the micro-controller that the portable electronic device is slanted if the portable electronic device is slanted to the second angle.
5. The operation method according to claim 4 , wherein the second angle ranges between 30°˜45°.
6. A portable electronic device, comprising:
a ringing module started up at a pre-set time;
a g-sensor used for detecting whether the portable electronic device is slanted when the ringing module is started up;
an image capturing module; and
a micro-controller used for enabling the image capturing module to perform human-eye recognition if the portable electronic device is slanted, and for disabling the ringing module if human-eye recognition is performed successfully and lasts for a specific period.
7. The portable electronic device according to claim 6 , wherein the g-sensor detects whether the portable electronic device is supported such that the angle contained between the portable electronic device and a horizontal plane is larger than a first angle, and if the portable electronic device is supported such that the angle contained between the portable electronic device and the horizontal plane is larger than the first angle, the micro-controller determines that the portable electronic device is perpendicular to the horizontal plane.
8. The portable electronic device according to claim 7 , wherein the first angle ranges between 80°˜90°.
9. The portable electronic device according to claim 7 , wherein the g-sensor detects whether the portable electronic device is slanted to a second angle, and if the portable electronic device is slanted to the second angle, the micro-controller determines that the portable electronic device is slanted.
10. The portable electronic device according to claim 9 , wherein the second angle ranges between 30°˜45°.
